新冠疫情对中国城市的短期影响及城市恢复力评价
Short-term Impact of COVID-19 on Chinese Cities and Urban Resilience Evaluation
摘要
Abstract
Accurate and scientific evaluation of the short-term impact and recovery of Chinese cities from COVID-19 and revealing its spa-tio-temporal change characteristics can provide strong support for the study and assessment of urban economic situation and urban recovery in the"normal"epidemic prevention and control stage.We used the multi-source data,such as VIIRS nighttime light,PMI population migration data and air pollution,to construct epidemic impact and recovery indicators.Based on the outbreak in cities,we used geographical statistics and concentric-ring analysis to conduct empirical analysis on the urban economy heterogeneity at different spatio-temporal scales.The results show that the multi-source data integration index can effectively reflect the impact of epidemic on the city and the trend of urban recovery.In terms of spatial distribution,residential areas and suburbs are less affected,while central business and industrial areas are more affected.关键词
